fo alwtom iv may concern:

Be it known that I, GEORGE W. GREGORY, of Boston, county of Suffolk, State of Massa chusetts, have invented an Improvement in Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object a novel method of producing boots and shoes, whereby the points or inner ends'of the metal or other driven fastenings employed to unite the soles and uppers are concealed and do not appear at the surface of the inner sole to interfere with the foot and mar the stocking.

Figure l representsin side elevation ashoe; Fig. 2, a metal rim or clinching surface, and Figs. 3 and vet a cross-section ofthe shoe in process of construction.

In accordance with my invention, the inner sole, a, is channeled in fromits edge for about seven-eighths ofan inch, more or less, and pref-` erably entirely about the said sole from heel to toe and return, formingalip, b. In this channel and under its lip is placed a thin metal rim or elinching-surface, c, (see Fig. 2,) preferably made of sheet-steel, shaped to conform in outline with the shape of the inner sole. In Fig 2 the rim is show'n as divided at c, leaving it in one piece 5 but, if desired, the rim may be divided as shown by dotted line c, Fig. 2. The metal rim c is placed in thechannel of the innersole under the lip b. rlhe inner sole is laid upon and with the lip next the bottom of the last d. The upper e isdrawn over the last and inner sole, and its edges are secured to the inner sole by tacks f, driven through the upper and the thickest part of the channeled edge of the inner sole, and thepoints of the said tacks meet or strike the metal rim and are arrested or clinched against the said rim in the channel. The outer sole, g, suitably channeled, as shown at g', is placed 011 the lasted shoe, and is held there preferably by lasting-nails 71. The last d is now removed from the shoe, and the latter is placed upon or overa rotatable horn, k, of a nailing-machine for driving nailsor fastenings, or for inserting screws*for instance, a standard screw or cablewire machineandthelip b ofthe channel rests on the tip 'of the horn. Next, the metal or other driven solc-fastenings are driven through the outer sole, upper, and that part of the'inner sole between the upper and the metal rim in the channel, and the said fastenings so driven or inserted have their points or ends clinched against or arrested by the said metal rim c or clinching-snrface, leaving the lip b entire. The driven solefastenings having been clinched or arrested by the rim c, theshoe 6o is removed from the horn and the operator lifts the lip b, seizes the metal rim, and pulls it out of the channel of the inner sole, and the channel lip is thereafter brought down on the inner sole to overlap or cover the ends or 65 points of the tacks f, used in lasting, and also the driven fastenings. The tack f does not remain in the shoe, but merely holds temporarily the outer and inner soles together.

The sole applied outside the upper and in- 7o ner sole may be composed of one or morelayers or thicknesses of leather, and so also I desire it to be understood that I might make a nailed turned shoe on a horn by the aid of the metal rim. In this last-named class of shoe the one single sole which serves as the outer sole would be channeled, as is the inner sole,

a, Fig. 8, the metal rim or clinching-surface would be applied thereon, and the upper, wrong side ont, would be drawn aboutthe sole, So as'is the upper shown in Fig. 3, and the edges of the upper would be tacked to the said sole,

as at f. After this the last would be Withdrawn and the shoe be placed on a horn, and the edges of the upper would be united to the said sole by fastenings driven iirst into the edge of the upper, then through the main part of the edge of the sole, and be stopped or clinched on the metal rim rest-ing in the channel and between the lip b and the tip of the horn.- 9o After this the shoe Would be removed from the horn and turned to bring the upper right sideout, the metal rim would be removed, and the channel-lip b be pasted or connected in place, as it will also be in the shoe having the outer sole, g.

I do not broadly claim the employment of a metallic surface in a channel against which to clinch a nail or fastening; nor do I broadly claim concealing the points of nails in the ico channel in an inner sole.

I claim- 1. rihe improvement herein described in the manufacture of boots and shoes, it consisting in channeling` the inner sole, placing a metallic rini or elinohing-surfaee therein and the inner sole on the last, drawing the upper over the inner sole on the last, confining the upper in place about the inner soleapplying the outer sole to the last7 withdrawing thelast from the lasted shoe and placing the latter, with the metal rim or elinching surface therein, on a` horn, and driving the sole-fastenings through the outer solo, uppe and partially through the inner sole7 and stopping or clinehing their ends upon the said metal rini or elinching-suri'aee7 and then removing the shoe from the horn and tne metal rini i'roin the channel in the inner sole, substantially as described.

f2. .Thatimprovement in unitinga channeled sole and an upper, which consists in placing a metal rim or clinching-surfaee in the chanaanwas ings through the upper and partially through the sole, and stopping or clinehingthem on the metal rim, and removing the Shoe from the horn and the metal rini from the channel, suhstantially as described.

in testimony whereof I have signed my name to this speeiieation in the presence o1.'

two subscribing witnesses.
